"Learn thou! the Life is, spreading life through all; It cannot anywhere, by any means, Be anywise diminished, stayed, or changed. But for these fleeting frames which it informs with spirit deathless, endless, infinite, They perish. Let them perish, Prince! and fight! He who shall say, "Lo! I have slain a man!" He who shall think, "Lo! I am slain!" Those both know naught! Life cannot slay. Life is not slain!" Krishna - Bhagavad Gita (The Song Celestial: 2)
